Neutrino Flavor Ratio on Earth and at Astrophysical Sources

High Energy Physics - Phenomenology 2014-11-20 v1

Abstract

We present the reconstruction of neutrino flavor ratios at astrophysical sources. For distinguishing the pion source and the muon-damped source to the 3σ\sigma level, the neutrino flux ratios, Rϕ(νμ)/(ϕ(νe)+ϕ(ντ))R\equiv\phi(\nu_\mu)/(\phi(\nu_e)+\phi(\nu_\tau)) and Sϕ(νe)/ϕ(ντ)S\equiv\phi(\nu_e)/\phi(\nu_\tau), need to be measured in accuracies better than 10%.
